Antiperspirant/deodorant composition

ABSTRACT

A composition comprising at least one plant derived oil having a melting point of about −15 to about 38° C. in an amount of about 5% or less by weight; and at least one active chosen from antiperspirant actives and deodorant actives in an amount of about 0.5 to about 16% by weight of the composition on an active weight basis. The composition can be used as an antiperspirant and/or deodorant when applied to an axillary area of a person.

BACKGROUND OF THE INVENTION

Antiperspirant and/or deodorant compositions are used to reduce thesweat in an axillary (underarm) region and/or to kill bacteria in thisregion to reduce or eliminate body odor caused by bacterial growth inthis region. Antiperspirants/deodorants can be provided in many forms,such as a roll on, a gel, or as a solid stick. These compositions areapplied to the axillary region, and they dry as the volatile carriersevaporate away to leave the active material. When roll on or gelcompositions dry, they can leave the skin feeling tacky with a wetfeeling.

It would be desirable to provide an antiperspirant/deodorant compositionthat reduces or eliminates the tacky and or wet feeling, and inparticular for roll-on applications where the water content is usuallymore than 50% of the formula.

BRIEF SUMMARY OF THE INVENTION

A composition comprising:

-   a) at least one plant derived oil having a melting point of about    −15 to about 38° C. in an amount of about 5% or less by weight; and-   b) at least one active chosen from antiperspirant actives and    deodorant actives in an amount of about 0.5 to about 22% by weight    of the composition on an active weight basis.

DETAILED DESCRIPTION OF THE INVENTION

As used throughout, ranges are used as a shorthand for describing eachand every value that is within the range. Any value within the range canbe selected as the terminus of the range. References to amounts inpercentages throughout this specification are based on the active weightof the material to the total weight of the composition, except forsurfactants, which are based on as supplied.

The composition can be a liquid or a gel. In the liquid form, thecomposition can be formulated to be a roll on antiperspirant and/ordeodorant. In the liquid form, the composition can be an oil in wateremulsion or a water in oil emulsion. In one embodiment, the compositionis an oil in water liquid emulsion. In gel form, the composition can beanhydrous or aqueous. The liquid can be contained in any roll ondispenser that has a ball for applying the composition to the surface ofthe skin.

In one embodiment, the composition excludes glycerin (glycerol),sorbitol, ethylene glycol, propylene glycol, sunflower oil, borage seedoil, and combinations thereof. When present in sufficient amounts, thesematerials increase the tackiness of the composition as well as productdry-down time. Also, addition of these components do not add structureto the composition.

The composition includes a plant derived oil having a melting point ofabout −15 to about 38° C., which is an oil that is obtained from a plantor is a synthetically manufactured equivalent. As used herein, the termoil includes materials that are defined as a liquid wax. For example,jojoba oil can be referred to as a liquid wax. The methyl and ethylesters of plant derived oils are also included in the definition of aplant derived oil. This plant derived oil can provide structure to thecomposition. In one embodiment, this material is present in an amount ofabout 5% or less by weight of the composition. Levels much higher than5% will give an oily/greasy feel to the composition and give anincreased dry time. In one embodiment, the amount of plant derived oilis about 1 to about 3% by weight of the composition. Examples of theplant derived oil include, but are not limited to, soybean oil, jojobaoil, coconut oil, safflower oil, palm kernel oil, cottonseed oil, andpine nut oil. In certain embodiments, the plant derived oils arepartially hydrogenated versions of theses oils. Lower levels ofunsaturation can reduce potential chemical interaction with otherroll-on components and can also reduces the tendency for the oil tooxidize and form a rancid odor that is harder to fragrance. The iodinevalue and percent saturates (which are inversely proportional to eachother) are two means of describing the degree of hydrogenation presentin the plant derived oil.

The presence of the plant derived oil reduces the tackiness of theantiperspirant active, which is found in the aqueous phase. The additionof optional emollients in combination with the plant derived oil canalso give this desired effect when the total amount of emollient and theplant derived oil is about 5% or less. The tackiness is determined by anexpert sensory panel comprised of at least 10 trained panelists whoassess the skin feel properties of the formulas. One of the productcharacteristics measured in the test, both on forearm and axillary, istackiness. The trained panelist assesses the tackiness of the product byfeeling the product with her fingertips at given time intervals andrating the tackiness on a scale of 0 (no tack) to 10 (very tacky).

Ameliorating the wet feeling can also be achieved by providing somestructure and body to the formula that the wearer perceives as providinga richness to the formula.

In one embodiment, the plant derived oil is selected to be partiallyhydrogenated and have a melting point that is about −15° C. (5° F.) toabout 38° C. (100° F.). In another embodiment, the melting point isabout 26° C. (80° F.) to about 35° C. (95° F.). To obtain the desiredmelting point, the plant derived oil can be partially hydrogenated or ablend of non-hydrogenated with partially or fully hydrogenated oilsand/or waxes.

In one embodiment, the plant based oil comprises a partiallyhydrogenated soybean oil having an iodine value in the range of about 75to about 80. Iodine value can be measured by ASTM D5554-95 (2006). Thispartially hydrogenated soybean oil can be obtained from Cargill underthe product designation S-500. This material has a typical fatty aciddistribution shown in the table below. Amounts shown are in % by weight.

Another benefit of using a partially hydrogenated plant oil such assoybean oil is that it can provide structure, in the form of increasedviscosity, to the composition. Viscosity or structure of a liquidcomposition is measured in mPas (centipoise) by a Brookfield Viscometerat 23° C. using spindle 4 at an RPM setting of 20. Viscosity of a gelcomposition is measured in Pa (G′ and G″) by an AR 1000 rheometer at 21°C. using an oscillatory mode.

An additional benefit of using a partially hydrogenated plant oil suchas soybean oil within the present invention is the ease of fragrancingthe composition. The reduced level of malodor formed during the aging ofthe composition when formulating with partially hydrogenated plant oils,allows for the fragrance to provide great fragrance hedonics withouthaving to also cover the malodor. Partially hydrogenated plant oils havea lower iodine value, which corresponds to fewer double bonds. Thereduced number of double bonds provides for a lower propensity forfragrance degradation.

Any surfactant that can be used in antiperspirant and/or deodorantcompositions can be included. The surfactant can be included in anydesired amount. In one embodiment, the amount of surfactant is about 2to about 12% by weight of the composition. The amount in the compositionis based on the as supplied material. In another embodiment, the amountof surfactant is about 3 to about 10% by weight. In one embodiment, whenthe composition is an oil in water roll-on formula, the amount ofsurfactant is about 2 to about 5%. In one embodiment, when thecomposition is a water in oil gel composition, the amount of surfactantis about 3 to about 10%. Examples of the surfactant include, but are notlimited to, nonionic surfactants, silicone surfactants, and combinationsthereof.

Nonionic surfactants that can be used include, but are not limited to,(a) sorbitan esters and ethoxylated sorbitan esters (for example PEG-20sorbitan isostearate, sorbitan monolaurate, polysorbate-20,polysorbate-40, polysorbate-60, polysorbate-80); (b) ethoxylates (forexample, Ceteth-20, PEG-30 castor oil, PEG-40 hydrogenated castor oil,PEG-60 hydrogenated castor oil, Laureth-7, Isolaureth-6, Steareth-10,Steareth-20, Steareth-21, Steareth-100, Ceteareth-12, Oleth-5,Oleth-10); (c) ethoxylated adducts (for example, PEG-25 stearate,glyceryl stearate and PEG-100 stearate); (d) PEG esters (for example,PEG-8 oleate, PEG-8 laurate, PEG-8 dilaurate, PEG-12 dilaurate, PEG-80diisostearate, PEG-40 stearate); (e) propoxylates (for example, PPG-10butanediol, PPG-50 oleyl ether, PPG-2-ceteareth-9, PPG-3-deceth-3,PPG-5-ceteth-20); (f) ethoxylated modified triglycerides (for example,PEG-20 corn glycerides, PEG-12 palm kernel glycerides); (g) alkylphenolaromatic ethoxylates (for example, dinonylphenol ethoxylate with 9 molesof EO, octylphenol ethoxylate with 20 moles of EO, octylphenolethoxylate with 40 moles of EO); (h) block copolymers that arealkoxylated glycols having ethoxylated and propoxylated segments (forexample, POLOXAMER™182 and 234, POLOXAMER™105 Benzoate, andMEROXAPOL™174); and combinations thereof. In one embodiment, thenonionic surfactant is selected so that it has an HLB(hydrophilic-lipophilic balance) value of 8-16 (more particularly 8-12).

In one embodiment, the nonionic surfactant is selected from ethoxylatednon-ionic surfactants and propoxylated non-ionic surfactants. Example ofthese include, but are not limited to Steareth 2, Steareth 20, andSteareth 21. In an oil in water composition embodiment, a combination of2 surfactants, one having an HLB value of about 2 to about 8 (such asSteareth 2) and the other having an HLB of about 9 to about 18 (such asSteareth 20 and 21), can be used.

Examples of silicone surfactants can be found in U.S. Pat. No.6,485,716, which is incorporated herein by reference only for thelisting of the silicone surfactants. Suitable silicone surfactantsinclude silicone polyglucosides (for example, octyl dimethicone ethoxyglucoside) and silicone copolyols having an HLB value (hydrophiliclipophilic balance) ≦8. The HLB value may be measured in a variety ofways such as described in conventional references or found listed intables of data recording such values. It is intended that any type ofHLB measurement technique may be used.

In general, silicone copolyols include, but are not limited to,copolyols of the following Formulae I and II. Formula I materials may berepresented by:(R¹⁰)₃SiO[(R¹¹)₂SiO]_(x)Si(R¹²)(R^(b)O(C₂H₄O)_(p)(C₃H₆O)_(s)R^(c))O]_(y)Si(R¹³)₃wherein each of R¹⁰, R¹¹, R¹², and R¹³ may be the same or different andeach is chosen from C1-C6 alkyl; R^(b) is the radical —C._(m)H_(2m)—;R^(c) is a terminating radical which can be hydrogen, an alkyl group ofone to six carbon atoms, an ester group such as acyl, or an aryl groupsuch as phenyl; m has a value of two to eight; p and s have values suchthat the oxyalkylene segment —(C₂H₄O)_(p)—(C₃H.₆O)._(s)— has a molecularweight in the range of 200 to 5,000; the segment preferably having fiftyto one hundred mole percent of oxyethylene units —(C₂H₄O)_(p)— and oneto fifty mole percent of oxypropylene units —(C₃H₆O)._(s)—; x has avalue of 8 to 400; and y has a value of 2 to 40. Preferably each of R¹⁰,R¹¹, R¹², and R¹³ is a methyl group; R^(c) is H; m is preferably threeor four whereby the group R^(b) is most preferably the radical —(CH₂)₃—;and the values of p and s are such as to provide a molecular weight ofthe oxyalkylene segment —(C₂H₄O)_(p)—(C₃H₆O)_(s)— of between about 1,000to 3,000. In one embodiment, p and s should each have a value of about18 to 28. In one embodiment, the silicone copolyol is dimethiconecopolyol.

A second siloxane polyether (copolyol) has the Formula II:(R¹⁰)₃SiO[(R¹¹)₂SiO]_(x)Si(R¹²)(R^(b)O(C₂H₄O)_(p)R^(c))O]_(y)Si(R¹³)₃wherein p has a value of 6 to 16; x has a value of 6 to 100; and y has avalue of 1 to 20 and the other moieties have the same definition asdefined in Formula I.

It should be understood that in both Formulas I and II shown above, thatthe siloxane-oxyalkylene copolymers may, in alternate embodiments, takethe form of endblocked polyethers in which the linking group R^(b), theoxyalkylene segments, and the terminating radical R^(c) occupy positionsbonded to the ends of the siloxane chain, rather than being bonded to asilicon atom in the siloxane chain. Thus, one or more of the R¹⁰, R¹¹,R¹², and R¹³ substituents that are attached to the two terminal siliconatoms at the end of the siloxane chain can be substituted with thesegment —R^(b)—O—(C₂H₄O)_(p)—(C₃H₆O)_(s)—R^(c) or with the segment—R^(b)—O—(C.₂H.₄O)_(p)—R.^(c). In some instances, it may be desirable toprovide the segment —R^(b)—O—(C₂H₄O)_(p)—(C₃H₆O)_(s)—R^(c) or thesegment —R^(b)—O—(C₂H₄O)_(p)—R^(c) at locations which are in thesiloxane chain as well as at locations at one or both of the siloxanechain ends.

Particular examples of suitable dimethicone copolyols are availableeither commercially or experimentally from a variety of suppliersincluding Dow Corning Corporation, Midland, Mich.; General ElectricCompany, Waterford, N.Y.; Witco Corp., Greenwich, Conn.; and GoldschmidtChemical Corporation, Hopewell, Va. Examples of specific productsinclude DOW CORNING 5225C from Dow Corning, which is a 10% dimethiconecopolyol in cyclomethicone; DOW CORNING 2-5185C, which is a 45-49%dimethicone copolyol in cyclomethicone; SILWET L-7622 from Witco; ABILEM97 from Goldschmidt, which is a 85% dimethicone copolyol in D5cyclomethicone; and various dimethicone copolyols available eithercommercially or in the literature.

It should also be noted that various concentrations of the dimethiconecopolyols in cyclomethicone can be used. While a concentration of 10% incyclomethicone is frequently seen commercially, other concentrations canbe made by stripping off the cyclomethicone or adding additionalcyclomethicone. The higher concentration materials such as DOW CORNING2-5185 can be used in one embodiment.

In one embodiment, 0.5-5 weight % (particularly 1.0-2.0%) of a 10%silicone copolyol such as dimethicone copolyol in cyclomethicone mixturemay be used, wherein the amount of mixture added is selected so that thelevel of silicone copolyol in the composition is in the range of0.05-0.5% (particularly 0.1%) (for example, 1% of a 10% dimethiconecopolyol in cyclomethicone mixture).

The composition can additionally include a betaine. The betaine of thisinvention is not a surfactant. Betaine in IUPAC nomenclature is1-carboxy-N,N,N-trimethylmethanaminium hydroxide-inner salt, withalternative names including carboxymethyl-trimethyl-ammonium betaine or(carboxymethyl)trimethylammonium hydroxide-inner salt or glycine betaineor glycol betaine or glycyl betaine or trimethyl glycine ortrimethylglycoll. For convenience here, the material of Formula A(C₅H₁₁NO₂; Mass=117.08 amu; molecular weight=117.15; analysis as C:51.26; H: 9.46; N: 11.96; O: 27.32) will be referred to as Betaine.

The hydrochloride form is also included in the scope of this invention.The hydrochloride form may be represented by Formula Aa, and it will bereferred to as Betaine Hydrochloride:

The use of betaine will refer to the Betaine of Formula A or the BetaineHydrochloride of Formula Aa. More information about the betaine can befound in U.S. Pat. No. 6,969,510, which is incorporated herein byreference only for its disclosure of Betaine.

The betaine can be included in the composition in any desired amount. Inone embodiment, the combined amount of plant oil and/or wax with betaineis about 10% by weight of the composition or less. In anotherembodiment, the combined amount is about 4 to about 8% by weight. Inanother embodiment, the weight ratio of betaine to plant oil and/or waxis 3:1 to 1:1.

The composition can additionally include ionizable inorganic salts.These ionizable salts are of the form M_(a)X_(b) where a=1, or 2 and b=1or 2; M is a member chosen from Na⁺¹, Li⁺¹, K⁺¹, Mg⁺², Ca⁺², Sr⁺², andZn⁺² and X is a member chosen chloride, bromide, iodide, citrate,gluconate, lactate, glycinate, glutamate, ascorbate, aspartate, nitrate,phosphate, hydrogenphosphate, dihydrogenphosphate, formate, maloneate,maleate, succinate, carbonate, bicarbonate, sulfate, andhydrogensulfate. In certain embodiments, the selected salts are chosenfrom NaCl and ZnCl₂. As will be appreciated by those skilled in the art,while it may be possible under certain circumstances to add a saltdirectly to a portion of the mixture during manufacturing, it is desiredto add the salt as a mixture or solution of the salt in a carrier orsolvent, particularly water. Of course various concentrations of thesalt premix can be made.

When the composition includes an antiperspirant active, any of the knownantiperspirant active materials can be utilized in the composition.Antiperspirant actives include, but are not limited to, aluminumchlorhydrate, aluminum chloride, aluminum sesquichlorohydrate,aluminum-zirconium hydroxychlorides, complexes or adducts of theabove-mentioned active ingredients with glycol, such as propylene glycol(for example, “Rehydrol” II from Reheis Chemical Co.), and combinationsthereof. Known aluminum-zirconium salts in combination with neutralamino acids, such as glycine (e.g., aluminum-zirconium tetrachlorohydrexGly) can also be used. Generally, any of the Category I activeantiperspirant ingredients, listed in the Food and Drug Administration'sMonograph on Antiperspirant Drug Products for overall-the-counter humanuse (Oct. 10, 1973) can be used.

In other embodiments, the antiperspirant active is an aluminum saltand/or an aluminum-zirconium salt, such as those described above, thatare further stabilized by betaine and a calcium salt. More informationabout betaine and calcium salt stabilized antiperspirant salts can befound in U.S. Patent Application Publication No. 2006/0204463 to Tang etal., which is incorporated herein by reference only for the disclosureof the antiperspirant actives.

In other embodiments, the antiperspirant active, such as those describedabove, is selected to have a low metal to chloride ratio. Examples ofthese antiperspirant actives can be found in U.S. Pat. No. 6,375,937 toChopra et al. and in U.S. Patent Application Publication No.2004/0109833 to Tang et al., which are incorporated herein by referenceonly for their disclosure of the antiperspirant active.

In other embodiments, the type of salt of interest, an aluminumzirconium tetrasalt or octasalt free of glycine are used whereinaluminum zirconium salt is stabilized by Betaine and has a metal tochloride ratio of about 0.9:1 to about 1.3:1 (and in other embodimentsof about 0.9:1 to about 1.2:1 or about 0.9:1 to about 1.1:1). For thetetrasalt, the Al/Zr atomic ratio can be about 3.2:1 to about 4.1:1.0and the Betaine:zirconium mole ratio can be about 0.2:1 to about 3.0:1(or in other embodiments of about 0.4:1 to about 1.5:1). Another saltthat can be used is an aluminum chloride salt buffered by Betaine,wherein the salt has a metal to chloride ratio of 0.9:1 to 1.3:1 (and inother embodiments of about 0.9:1 to about 1.2:1 or about 0.9:1 to about1.1:1). For the octasalt the Al/Zr atomic ratio is about 6.2:1 to about10.0:1 and the Betaine:Zr mole ratio is about 0.2:1 to about 3.0:1 (orin other embodiments of about 0.4:1 to about 1.5:1). In one embodiment,in the case of a salt that contains zirconium, the Betaine isincorporated during the synthesis of the salt so as to maximize thestabilizing effect this ingredient has (especially on the zirconiumspecies). Alternatively, it can be post added to a glycine-free saltalong with additional active phase ingredients to form a Betainestabilized active.

Examples of commercially available glycine-free low M:Cl ratiotetrasalts and octasalts include, but are not limited to, REZAL™ AZP 955CPG and REZAL™ AZP 885 respectively (both from Reheis Chemical Company,Berkeley Heights, N.J.). A more detailed description of making suchcommercially available salts can be found for example, in U.S. Pat. Nos.7,074,394 and 6,960,338. Further examples of making these types of saltcomplexes are described in U.S. Patent Application Publication No.2004/0198998 and U.S. Pat. No. 7,105,691.

In addition to the anti-irritation properties of Betaine, it has alsobeen found that antiperspirant formulations preserve their fragrancestability upon ageing when the Al/Zr salt is used in association withBetaine.

Additionally, the antiperspirant active can be a calcium salt stabilizedantiperspirant active. Examples of calcium salt stabilizedantiperspirant actives can be found in U.S. Patent ApplicationPublication No. 2006/0204463, which is incorporated herein by referenceonly for the disclosure of the calcium salt stabilized antiperspirantactives.

In addition, any new ingredient, not listed in the Monograph, such asaluminum nitratohydrate and its combination with zirconylhydroxychlorides and nitrates, or aluminum-stannous chlorohydrates, canbe incorporated as an antiperspirant active. Antiperspirant actives caninclude, but are not limited to, the following: astringent salt ofaluminum, astringent salt of zirconium, aluminum bromohydrate, aluminumchlorohydrate, aluminum dichlorohydrate, aluminum sesquichlorohydrate,aluminum chlorohydrex PG, aluminum dichlorohydrex PG, aluminumsesquichlorohydrex PG, aluminum chlorohydrex PEG, aluminumdichlorohydrex PEG, aluminum sesquichlorohydrex PEG, aluminum chloride,aluminum sulfate, aluminum zirconium chlorohydrate, aluminum zirconiumtrichlorohydrate, aluminum zirconium tetrachlorohydrate, aluminumzirconium pentachlorohydrate, aluminum zirconium octachlorohydrate,aluminum zirconium tetrachlorhydrex propylene glycol, aluminum zirconiumtrichlorohydrex Gly, aluminum zirconium tetrachlorohydrex Gly, aluminumzirconium pentachlorohydrex Gly, aluminum zirconium octachlorohydrexGly, buffered aluminum sulfate, potassium alum, sodium aluminumchlorohydroxy lactate. In one embodiment, the antiperspirant active isaluminum chlorhydrate. In another embodiment, the antiperspirant activeis aluminum zirconium tetrachlorhydrex propylene glycol.

Examples of deodorant active include, but are notlimited to antimicrobial actives, alcohols, 2,4,4′-trichloro-2′-hydroxydiphenyl ether (Triclosan), octoxyglycerin (SENSIVA™ SC 50).benzethonium chloride, polyhexamethylene biguanides, triethylcitrate,2-amino-2-methyl-1-propanol (AMP), cetyl-trimethylammonium bromide,cetyl pyridinium chloride, bactericides, and bacteriostats.

The composition may also contain particulates which include but are notlimited to talc, mica, fragrance encapsulates, or hydrophobicallymodified starches, such as aluminum starch octenyl succinate (MACKADERM™ASTRO-DRY™ from McIntyre Group Ltd.). If the composition is in a liquidform and dispensed through a roll-on applicator, the average particlesize of the suspended material is sized so that it can pass through theapplication to prevent the ball applicator from malfunctioning. Usually,the average particle size does not exceed 150 microns.

In certain embodiments, the composition may also contain as an optionalingredient at least one malodor counteracting alpha, beta-unsaturatedester or mixtures of such materials. In certain embodiments, the levelof malodor counteracting composition to deliver a perceivable odorcontrol benefit when delivered from an antiperspirant and/or deodorantcomposition is about 0.05 to about 0.45 weight % based on the entirecomposition. The alpha, beta-unsaturated ester malodor counteractingmaterials are incorporated within the oil phase of an antiperspirantcomposition. Example of these malodor counteracting components can befound in U.S. Pat. No. 6,610,648 and U.S. Pat. No. 6,495,097, which areincorporated herein only for their disclosure of the alpha, betaunsaturated esters. For example, in this invention the odor neutralizingalpha, beta unsaturated ester mixture demonstrates unexpected stabilityin antiperspirant compositions containing low metal:chloride (M:Cl)ratio salts free of glycine. Examples of the alpha, beta unsaturatedester can be found in WO2005/025523, which was filed in the U.S. as U.S.application Ser.

In one embodiment,

In one embodiment, the emollient is selected from linear silicones,cyclic silicones, hydrocarbons, polyhydroxy alcohols having more than 3carbon atoms, liquid or solid polyalkyleneglycol ethers containing apolypropylene glycol (PPG) moiety and terminating in an alkyl ether, andcombinations thereof. In another embodiment, the emollient is a volatilesilicone having a flash point of 100° C. or less, such as cyclomethiconeor trisiloxane. In another embodiment, the emollient is a nonvolatilesilicone, such as dimethiconol or a longer chain dimethicone.

By volatile silicone material is meant a material that has a measurablevapor pressure at ambient temperature. For the volatile siliconeportion, examples of volatile silicones (particularly silicones with aflash point of 100° C. or less at atmospheric pressure) includecyclomethicone (especially cyclopentasiloxane, also called “D5”),“hexamethyldisiloxane”, and low viscosity dimethicone (for example, DowCorning 200 fluid having a viscosity of 0.5-5 centistokes). Suchvolatile silicones include conventional cyclic and linear volatilesilicones. Illustratively, and not by way of limitation, the volatilesilicones are one or more members chosen from cyclicpolydimethylsiloxanes such as those represented by Formula III:

where n is an integer with a value of 3-7, particularly 5-6. Forexample, DC-245 fluid (or the DC-345 version) from Dow CorningCorporation (Midland, Mich.) is a type of cyclomethicone which can beused. These include a tetramer (or octylmethylcyclotetrasiloxane) and apentamer (or decamethylcyclopentasiloxane). The volatile linearsilicones can also be included in this group of volatile silicones andare one or more members chosen from linear polydimethylsiloxanes such asthose represented by Formula IV:

which have a viscosity of 0.5-5 centistokes.

Examples of such volatile silicones include one or more members selectedfrom D4, D5, and D6 cyclomethicones; and linear dimethicones having aviscosity in the range of 0.5-5 centistokes.

Making Procedure

-   1. Aqueous Phase: Mix together DI Water & Surfactants:    -   a. Heat Part 1 of water to 84-85° C.    -   b. Melt and add to heated water the water phase surfactant (i.e.        Steareth 20) Mix until solids are completely dissolved.    -   c. Maintain temperature at 80-84 C.-   2. Oil Phase: Mix together emollients and surfactant.    -   a. Weigh out PPG 15.    -   b. Melt oil phase surfactants (i.e. Steareth 2), add to PPG-15.    -   c. Add emollients and plant derived oils un-melted.    -   d. Add BHT    -   e. Heat to 50° C. while mixing all the ingredients.    -   f. Continue mixing, bring temperature to 64-66° C.-   3. Using a **Rustin disk, add Oil phase to Aqueous phase under high    shear mixing (360 rpm). Addition rate: approximately 20 g/min. Stop    heating. Decrease mixing speed to 320 rpms.-   4. When temperature drops to 68-70° C., add EDTA solution, continue    mixing at 320 rpm.-   5. Active Phase addition    -   a. Increase mixing speed to 350 rpm, and slowly add part 2 of        water—(cool).    -   b. Add antiperspirant active ingredient, continue mixing at 350        rpm.    -   c. Let temperature drop to 44-46° C.    -   d. Slow down mixing speed to 320 rpms. Add Quaternium 15        solution.    -   e. When temperature is 35° C. or below, slowly add fragrance        using a dropper, continue mixing at 320 rpm.    -   f. Continue mixing for additional 10-15 minutes after addition        of fragrance is complete.

Alternatively, a homogenization step can be incorporated between steps 3and 4. Using a Silverson homogenizer, homogenize for 5 minutes afteraddition of the oil phase is complete.

Alternatively, the antiperspirant active solution can also be addedalong with the water and aqueous phase surfactants.
